摘要

Device (136) for treatment of water, preferably a reverse osmosis device (310) comprises at least one membrane module (318) for generating permeate and concentrate, which is integrated at least partially in a dishwashing machine and exhibits a pump (316). A permeate recirculation is provided with a passive obturator, which supplies the permeate at a feed point (314) upstream to the pump. An independent claim is also included for operating the dishwashing machine with the device for the treatment of water, comprising opening the valve in the permeate recirculation during the non-discharge of the permeate through the dishwashing machine, supplying the permeate to an input side of the pump, and carrying out backwashing with permeate.
